callback hell javascript

// defination 
Callback hell is a phenomenon that afflicts a JavaScript developer
when he tries to execute multiple asynchronous operations one after the other.
By nesting callbacks in such a way,
we easily end up with error-prone, hard to read,
and hard to maintain code.Soln: Best code practice to handle it.
//example
const makeBurger = nextStep => {
  getBeef(function(beef) {
    cookBeef(beef, function(cookedBeef) {
      getBuns(function(buns) {
        putBeefBetweenBuns(buns, beef, function(burger) {
          nextStep(burger);
        });
      });
    });
  });
};
